In this regard, the use of mechanical joining processes, such as clinching, enable assembly sheet metals to achieve strength properties similar to those of established thermal joining technologies. However, to guarantee a high reliability of the generated joint connection, the selection of a best-fitting joining technology as well as the meaningful description of individual joint properties is essential. In the context of clinching, few contributions have to date investigated the metamodel-based estimation and optimization of joint characteristics, such as neck or interlock thickness, by applying machine learning and genetic algorithms. Therefore, several regression models have been trained on varying databases and amounts of input parameters. However, if product engineers can only provide limited data for a new joining task, such as incomplete information on applied joining tool dimensions, previously trained metamodels often reach their limits. This often results in a significant loss of prediction quality and leads to increasing uncertainties and inaccuracies within the metamodel-based design of a clinch joint connection. Motivated by this, the presented contribution investigates different machine learning algorithms regarding their ability to achieve a satisfying estimation accuracy on limited input data applying a statistically based feature selection method. Through this, it is possible to identify which regression models are suitable to predict clinch joint characteristics considering only a minimum set of required input features. Thus, in addition to the opportunity to decrease the training effort as well as the model complexity, the subsequent formulation of design equations can pave the way to a more versatile application and reuse of pretrained metamodels on varying tool configurations for a given clinch joining task.","lang":"eng"}],"publication":"AI","issue":"4","type":"journal_article","keyword":["Industrial and Manufacturing Engineering"],"date_created":"2022-12-14T12:32:29Z","intvolume":"         3","date_updated":"2022-12-14T13:43:53Z","publication_status":"published","author":[{"full_name":"Zirngibl, Christoph","last_name":"Zirngibl","first_name":"Christoph"},{"last_name":"Schleich","first_name":"Benjamin","full_name":"Schleich, Benjamin"},{"first_name":"Sandro","last_name":"Wartzack","full_name":"Wartzack, Sandro"}],"publication_identifier":{"issn":["2673-2688"]},"title":"Estimation of Clinch Joint Characteristics Based on Limited Input Data Using Pre-Trained Metamodels","year":"2022","doi":"10.3390/ai3040059","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://www.mdpi.com/2673-2688/3/4/59"}]},{"volume":22,"user_id":"89037","publication_date":"2022-11-15","language":[{"iso":"eng"}],"_id":"34549","main_file_link":[{"url":"http://www.sehepunkte.de /2022/11/36727.html","open_access":"1"}],"intvolume":"        22","date_updated":"2022-12-19T11:01:55Z","author":[{"last_name":"Schönhärl","first_name":"Korinna","orcid":"0000-0002-7967-3261","full_name":"Schönhärl, Korinna","id":"89037"}],"title":"Review on: Daniel Benedikt Stienen: Verkauftes Vaterland","status":"public","year":"2022","department":[{"_id":"445"}],"oa":"1","type":"review","date_created":"2022-12-19T11:01:46Z","quality_controlled":"1","citation":{"short":"K.

To protect the communication of people, companies, and states from such threats, we require cryptography with strong security guarantees.\r\nDifferent applications may require different security properties from cryptographic schemes.

Recent results indicate an ever increasing predictive ability of current approaches on benchmark datasets. However, this effectiveness often comes with the cost of over-parameterization and increased computationally complexity. The former induces extensive hyperparameter optimization to mitigate malicious overfitting. The latter magnifies the importance of winning the hardware lottery. Here, we investigate a remedy for the first problem. We propose a technique based on Kronecker decomposition to reduce the number of parameters in a knowledge graph embedding model, while retaining its expressiveness. Through Kronecker decomposition, large embedding matrices are split into smaller embedding matrices during the training process. Hence, embeddings of knowledge graphs are not plainly retrieved but reconstructed on the fly. The decomposition ensures that elementwise interactions between three embedding vectors are extended with interactions within each embedding vector. This implicitly reduces redundancy in embedding vectors and encourages feature reuse. To quantify the impact of applying Kronecker decomposition on embedding matrices, we conduct a series of experiments on benchmark datasets. Our experiments suggest that applying Kronecker decomposition on embedding matrices leads to an improved parameter efficiency on all benchmark datasets. Moreover, empirical evidence suggests that reconstructed embeddings entail robustness against noise in the input knowledge graph. To foster reproducible research, we provide an open-source implementation of our approach, including training and evaluation scripts as well as pre-trained models in our knowledge graph embedding framework."}],"publication":"arXiv:2205.06560","citation":{"bibtex":"@article{Demir_Lienen_Ngonga Ngomo_2022, title={Kronecker Decomposition for Knowledge Graph Embeddings}, journal={arXiv:2205.06560}, author={Demir, Caglar and Lienen, Julian and Ngonga Ngomo, Axel-Cyrille}, year={2022} }","ama":"Demir C, Lienen J, Ngonga Ngomo A-C.

Across various domains, corresponding methods have proven effective and achieve state-of-the-art performance. However, pseudo-labels typically stem from ad-hoc heuristics, relying on the quality of the predictions though without guaranteeing their validity. One such method, so-called credal self-supervised learning, maintains pseudo-supervision in the form of sets of (instead of single) probability distributions over labels, thereby allowing for a flexible yet uncertainty-aware labeling. Again, however, there is no justification beyond empirical effectiveness. To address this deficiency, we make use of conformal prediction, an approach that comes with guarantees on the validity of set-valued predictions. As a result, the construction of credal sets of labels is supported by a rigorous theoretical foundation, leading to better calibrated and less error-prone supervision for unlabeled data. Along with this, we present effective algorithms for learning from credal self-supervision. An empirical study demonstrates excellent calibration properties of the pseudo-supervision, as well as the competitiveness of our method on several benchmark datasets."}],"citation":{"chicago":"Lienen, Julian, Caglar Demir, and Eyke Hüllermeier. “Conformal Credal Self-Supervised Learning.” <i>ArXiv:2205.15239</i>, 2022.","short":"J.

This thesis presents new results about Pareto critical sets for smooth and nonsmooth multiobjective optimization problems, both in terms of their efficient computation and structural properties. In the smooth case they are computed via a continuation method and in the nonsmooth case via a descent method. Afterwards, the structure of the boundary of the Pareto critical set is analyzed, which consists of Pareto critical sets of smaller subproblems. Finally, inverse problems are considered, where a data set is given and an objective vector is sought for which the data points are critical."}],"citation":{"apa":"Gebken, B.

In this process, the core structure, which is provided with stiffening ribs and functional elements, is formed and joined to two metal belts in one single step. For experimental validation of the concept, the development of a prototypic molding tool and the manufacturing of hybrid beams including process parameters are described. Three-point bending tests and optical measurement technologies are used to characterize the failure behavior and mechanical properties of the produced hybrid beams. It was found that the innovative IMA process enables the manufacturing of hybrid components with high energy absorption and low weight in one step.

To investigate current outcomes of Open Science research, and to get a better understanding on well-researched topics and research gaps, we aimed at providing an openly accessible overview of empirical studies that focus on different aspects of Open Science in different scientific disciplines, academic groups and geographical regions. In this paper, we describe a data set of studies about Open Science practices retrieved following a PRISMA approach to compile a literature review. We included studies from the Scopus and Web of Science databases with keywords relating to Open Science between the years 2000 and 2020, as well as a snowball search for relevant articles. Studies that did not investigate any aspect of Open Science, or weren’t peer-reviewed were excluded, resulting in a total of 695 remaining studies.<ns3:italic> </ns3:italic>The data set was collaboratively annotated to ensure intercoder reliability of the coded data.</ns3:p>"}],"publication":"F1000Research","doi":"10.12688/f1000research.121665.1","article_number":"535","main_file_link":[{"open_access":"1","url":"https://f1000research.com/articles/11-535"}],"language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2022-09-15T08:31:55Z","article_type":"original","intvolume":"        11","year":"2022","title":"MapOSR - A mapping review dataset of empirical studies on Open Science","author":[{"first_name":"Jana","last_name":"Lasser","full_name":"Lasser, Jana"},{"last_name":"Schneider","first_name":"Jürgen","full_name":"Schneider, Jürgen"},{"first_name":"Thomas","last_name":"Lösch","full_name":"Lösch, Thomas"},{"last_name":"Röwert","first_name":"Ronny","full_name":"Röwert, Ronny"},{"first_name":"Tamara","last_name":"Heck","full_name":"Heck, Tamara"},{"full_name":"Bluemel, Clemens","last_name":"Bluemel","first_name":"Clemens"},{"first_name":"Maike","last_name":"Neufend","full_name":"Neufend, Maike"},{"id":"90339","full_name":"Steinhardt, Isabel","first_name":"Isabel","orcid":"https://orcid.org/0000-0002-2590-6189","last_name":"Steinhardt"},{"full_name":"Skupien, Stefan","last_name":"Skupien","first_name":"Stefan"}],"publication_identifier":{"issn":["2046-1402"]}},{"language":[{"iso":"ger"}],"series_title":"Standards standardisierter und nichtstandardisierter Sozialforschung","main_file_link":[{"open_access":"1","url":"https://www.beltz.de/fachmedien/erziehungswissenschaft/produkte/details/48826-qualitative-und-quantitative-inhaltsanalyse-digital-und-automatisiert.html"}],"publication_identifier":{"eisbn":["978-3-7799-7037-8 E"]},"author":[{"full_name":"Schneijderberg, Christian","last_name":"Schneijderberg","first_name":"Christian"},{"full_name":"Wieczorek, Oliver","first_name":"Oliver","last_name":"Wieczorek"},{"id":"90339","full_name":"Steinhardt, Isabel","orcid":"https://orcid.org/0000-0002-2590-6189","last_name":"Steinhardt","first_name":"Isabel"}],"title":"Qualitative und quantitative Inhaltsanalyse: digital und automatisiert.

Warum sollten Sie also genau das vorliegende Methodenbuch „Qualitative und quantitative Inhaltsanalyse: digital und automatisiert “lesen? Erstens schließt dieses Buch eine Lücke, der wir in der Lehre und bei Methodenworkshops immer wieder begegnet sind. Diese Lücke besteht darin, dass selten eine Übersicht über und Gegenüberstellung verschiedener Methoden der qualitativen und quantitativen Inhaltsanalyse gegeben wird. Zudem haben bisherige Lehr-und Methodenbücher in den Sozialwissenschaften teil-und vollautomatisierte Verfahren der Textanalyse noch nicht aufgegriffen und diese mit bereits etablierten Verfahren qualitativer und quantitativer Inhaltsanalyse verknüpft. Zweitens bietet dieses Buch im ersten Teil eine systematische und anwendungsorientierte Einführung zu den Grundlagen inhaltsanalytischer empirischer Sozialforschung. Im zweiten Teil werden detaillierte Anleitungen von digital unterstützten qualitativen inhaltsanalytischen Auswertungstechniken gegeben. Den teil-und vollautomatisierten quantitativen inhaltsanalytischen Auswertungstechniken widmet sich der dritte Teil des Buches. Bei digital unterstützten Verfahren werden Sie durch Software bei Ihrer Analyse unterstützt, beispielsweise bei der digitalen Organisation Ihrer Daten und bei der digitalen Durchführung der Auswertung. Bei teilautomatisierten Verfahren der Inhaltsanalyse nehmen Ihnen Software und Tools Teile der Datenanalyse ab, wohingegen bei vollautomatisierten Verfahren der gesamte Auswertungsprozess und oftmals auch die Datenbeschaffung durch Programme und Tools durchgeführt wird."}],"publisher":"Beltz Juventa","_id":"33377","ddc":["300"],"user_id":"90339","status":"public","has_accepted_license":"1","place":"Weinheim, Basel","oa":"1","citation":{"short":"C.
